Hello @derlucas,

thank you very much for submitting this PR to us!

This is what will happen next:

1. My robotic colleagues will check your changes to see if they break anything. You can see the progress below.
2. Once that is finished, human contributors from paperless-ngx review your changes. Since this seems to be a small change, only a single contributor has to review your changes.
3. Please improve anything that comes up during the review until your pull request gets approved.
4. Your pull request will be merged into the dev branch. Changes there will be tested further.
5. Eventually, changes from you and other contributors will be merged into main and a new release will be made.

Please allow up to 7 days for an initial review. We're all very excited about new pull requests but we only do this as a hobby.
If any action will be required by you, please reply within a month.
